What script are you using to try to hide the button?
I created an hidden FIELD "online" that has the deault value = TRUE
then, I wrote:
root::preSave - (FormCalc, client)
then , I wrote
but it doesn't work
I would put the FALSE in quotes -> "FALSE" to make sure it's treated as a string.
I did it, but it doesnt work.
I think that the problem is in the pre-save event: it seems that sometimes it doesnt fire.
Than a lot
